Abstract
Formaldehyde is critically important to the chemistry of the urban atmosphere. During daylight, formaldehyde photolysis and decomposes to release the free radicals that drive photochemical ozone formation. With atmospheric lifetimes of few hours, formaldehyde is an important contributor to the radical formation that leads to high concentrations of ozone observed in urban environments, such as Houston. In addition, formaldehyde is a frequently used industrial chemical used in the manufacture of numerous building materials and household products.
